OK, just got back. Fantastic show!! I'll try and post some more detailed thoughts tomorrow.
That's so cool that everyone was able to follow along with the webcam! (The bright lights were when they turned the house lights up so they could be scared by the size of the crowd.) Arj mentioned this on his twitter, but he did have us all flip him the bird to see if we could set a record for most people flipping the bird at once. Did that show up on the webcam?
I took my camera, but got up there and realized the batteries were dead, but we were pretty far back, so they wouldn't have been too great.
We saw Arj signing stuff and talking to people, and the buses were parked by our parking lot, and it looked like they were set up to do a meet and greet. We decided to continue on home, but it didn't look like too many folks were sticking around, so if they did do it, I imagine that the holdouts got some quality time with the guys.
I'll post more tomorrow.
